Title: Color separation circuit
Inventor: KIRIYAMA TAKASHI
IPC: H04N9/00
Filed: 1990-03-30
Abstract: PURPOSE:To stably and accurately detect the phase shift of a color demodulation axis by correcting the reduction of the amplitude of an input analog color television signal by an AGC circuit. CONSTITUTION:The size of quantization errors e1 and e2 are inversely proportional to color burst amplitude A1 and A2, and assuming the color burst amplitude A1 as the amplitude of a color burst signal in a color television signal with the maximum amplitude, the color burst amplitude is reduced from A1 to A2 and the quantization error is increased from e1 to e2 when an input signal is decreased. Therefore, a function to correct the amplitude when the amplitude of the color burst of the input signal is decreased by the AGC circuit 4 is attached. Thereby, it is possible to detect the phase shift of the demodulation axis with high accuracy from the color burst.

Filed: 1984-04-26
Abstract: PURPOSE:To attain branching with a command issued on a truck by applying a DC signal to a steering control circuit of the truck according to the branching direction and giving deviation to the drive of the truck. CONSTITUTION:A plus or minus DC signal is produced according to the branching direction by a branch signal generating circuit 64 and by turning on a selection switch 643 or 644.
